Ta all 'whom z't may concern,"

Be it known that I, EDWARD II. J. Dir-LON, a citizen of the UnitedStates, residing at Philadelphia, in the county of Philadelphia, Stateof Pennsylvania, have invented certain new and useful Improvements inStorage Heaters; and I do hereby declare the following to be a full,clear, and exact description of the invention, such .as .will l@ enableothers skilled in the art to lwhich it appertains to make and use thesame.

This invention relates to storage heaters of lthekin'd employed forsupplying hot water or other liquid in quantity, and particularlystorage heaters of this kind in which the heat is vindirectly supplied,as by the condensation of steam in tubes projected into the shellforming the storage tank for the liquid to be heated. 20. The principalobject of the invention is to provide a heater of this character inwhich the heating tubes formingthe :so-called tube bundle may be readilywithdrawn from the storage shell for cleaning or repair by one 5 or twomen notwithstanding the weight and bulk of the tube bundle.

In storage heaters of comparatively large capacity, particularly whereexhaust-steam is used as the heating medium and there is 3 0consequently but a small difference between the steam and thetemperature to which the water is to be raised, the necessary tubesurface is large, and if the water to be heated is of a scale-formingcharacter the tubes must be cleaned at frequent intervals to obtainetlicient operation. In such heaters as now construetedit is a diiiculttask to remove the heavy bulky tube bundle without gasket employedbetween the tube supporting sheet'and wall of the shell. ',According tomy invention, I support the tube bundle in such a manner that it may bewithdrawn to a sufficient extent without lifting or suspending theweight of the tube bundle for the tubes to be readily cleaned, and maythen be guided in its return movement' in such a manner as to positionthe tube supporting sheet accurately on its seat without damage 0 to thelatter.l

In the accom anying drawings I have illustrated a preflrred embodimentof the invention, and a modification adapted forl different styles ofheaters.

1920. Serial No. 390,237.

Referring to the drawings; `Fig.v 1 is aside view of a storage heater,the tank being broken away, the tube bundle being sectioned;

Fig. 2 isa view showing the tube bundle drawn out of the tank;

Fig. 3 is anend View; Fig. 4C is a view similar to Fig. 1 showing amodification; and- Y Fig. 5 is a view of line 5 5 of Fig. 4. The tankfor the heating and storage of @5 the hot water is indicated at 1, andis preferably arranged in a horizontal position. One end of the -tank isprovided with an opening 2 through which the tube bundle is adapted tomove. rIhis opening is reinforced by an 7@ annular ring 3. The tubebundle, indicated at 4, comprises a number-of horizontal tubes supportedat their inner ends by the plate 5 and atAtheir-outer ends by the plate6. A dome-shaped cap 7 is mount/ed on the plate 5, the space within thecap being in communication with the ends of the several tubes of thetube bundle. 'Ihe cap is pro-v vided'with a supporting arm 8 which isinclined downwardly and outwardly as shown. f3@ The arm is provided witha roller 9 that moves on the track 10, positioned inside the tank andlongitudinally thereof. Associated with the supporting plate 6 isa capplate 11, these two plates being shaped as shown in Fig. 1 toaccommodate themselves to the angle of the end of the heater. Plates 6and V11 are provided with recesses which register toform the steam inletchamber 12 to which steam is led by the inlet pipe 13.

At the outer end of the tube bundle are two supporting arms 14 which areScrew 15 on the plate 1l and'with adjusting nuts 16, so thatthe outerend plates of the tube L bundle may be adjusted for accurate seating inthe end of the storage tank. The arms 14 are provided with rollers 17which move on as desired. v

'I-he heating medium which may conveniently be exhaust steam,enters-through the 105 pi e 13, is distributed through the tubes of thetu e bundle and passes into the space withinl the cap 7, thus heatingthe water within the e densed steam esca with inlet and outlet chambers24 and 25 out ot the tank, for

sag. Moreover, when the bundle is all thel way in the tank in normalposition the inner 1 -end'ot the bundle will not sag,

- all parts ot .With the. supporting arms formed by cooperation of theouter end plates 26 and 27. "lfhe inner end ot the tube bundle issupported by a plate 28, which in turn is supported by a downwardly andoutwardly inclined arm 29 provided with a roller 30 movable on the trackl0.

lFrom the constructions that have been described it will be apparentthat the tube bundle may be moved well out of the tank so as to beaccessible for scaling and repairs, both ends of the tube-bundle being'sup orted during the entire movement of the undle. Atny sagging of theinner end ofthe bundle is to be avoided, because it prevents accurateseating of the outer supporting plate and makes the in andout movementof the tank diiicult. By virtue ofthe tact that the inner end of thetube bundle is always supported, there is no tendency, when the bundleis half way out or all the way that end of the bundle to resulting 1nouter end plate. 8 and 29, as the case may be, inclined as shown, thetube bundle is projected well out of the tank so that itl are completelyaccessible, while at vthe same time the support Jfor the inner end isstill restingon the track inside ot the tank.v

While ll have illustrated two supports for the accurate seating of the lthe outer end ot' the bundle' and one support tor the-inner end, it, ofcourse, should be understood that this arrangement might, be reversed,or that various other supporting vdevices for the endsot the tube bundlemi ht 'be used. llt shuold alsobeunderstood t at other parts of theapparatus are not limited to the precise structure shown, but may beembodied in other forms, as falling within the scope of the followingclaims. i

lltis also to be understood thatvwhile the apparatus has been describedas` a water heater, it isnot limited to such use, but may obviously beemployed tor other purposes, and theinvention is in no wise limited tothe use of the apparatus for heating water.

l claim:

, l. ltn a water heater, the combination of a v tank, atubebundlemovableinto and vout et meneer the tank, means located within the tank tosupport the inner end of the tube' bundle during its movement, saidmeans comprising a supporting element associated with said bundle andcontacting with thestationary portion of the tank at a point materiallybeyond the end of said bundle, and means to vsupport the outer end ofthe bundle.

A 2. ll'n a water heater, the combination of a tank, a horizontal tubebundle movable into and out of the tank, a track within the tank,

'dle being movable on the outer track.

3. lin a water heater, the combination of a tank, a horizontal tubebundle movable into and out of the tank, means to support the outer-endof the bundle during its movement, an inclined supporting arm to supportthe inner end of the tube bundle, and a track located within the tank,-on which the inclined supporting arm moves.

i 4. lin a water heater, the combination of a tank, a horizontal tubebundle movable into and out'ot the tank, means within the tank tosupport the inner end of the tube bundle, and means to support the outerend of the tube bundle, said means comprising threaded supportingmembers and nuts on said members, whereby the height of the outer end of'said tube bundle may be changed by alter- `ing the position of saidnuts.

the combination of a movable into and 5. ln a water heater, tank, vaheating element out of thetank, and means within the tank4 to supportIthe inner end of said heating ele- -ment, said means comprising asupporting ment, said means comprising a supporting bracket projectinginwardly beyond the inner end of the heating element whereby the entireheating element may be AWithdrawn from thel tank without withdrawing thesupport from the tank, a roller carried by said bracket adapted to `rollalong the bottorn of said tank and tached to the ment and adapted tosupport the outer end ont the heating element as the heating ele-v mentis withdrawn. from the tank.
